@GerryMc: why for publication of whitepaper should wait Q4...?
That's when it is due to be published.
yesterday every open wallet is always missing, it turns out zixx-qt.exe directly erased by anti-virus, so now I do not use anti-virus, new wallet can be open, is there a case like me ..?
Most crypto wallets show a false positive on most antivirus programs. "Bitcoin miner" is a common reason. You can whitelist the program or the folder that the program is in.
